Need help debugging a stubborn software issue

I’m looking for a reliable IT freelancer in the UK to help diagnose and fix a recurring software issue on my workstation. The problem occurs intermittently with our internal tool, causing slow performance and occasional freezes. Ideally, you’d review the logs, reproduce the issue, and implement a stable workaround or patch. Familiarity with Windows/Mac environments, error tracing, and remote debugging is a plus. I’d prefer someone who can provide a brief report after the session and suggest long-term improvements to prevent future incidents. Flexible scheduling, but I’d like to start within the next couple of days. Context: The team relies on a custom internal app that connects to our database. We’ve already cleared cache, updated drivers, and checked network connectivity. If you have experience with similar debugging scenarios, please reach out with your approach and expected duration.
